Deficiency of vitamin E may cause extensive neuropathy in young children and, in addition, is suspect as a possible cause of motor and sensory neuropathy in older children and in adults. One likely cause of vitamin E deficiency is intestinal malabsorption, resulting from bowel disease, pancreatic disease, or chronic cholestasis. Other causes of malabsorption of vitamin E include celiac disease, cystic fibrosis, and intestinal lymphangiectasia.
